Title: A system for the circulation of an abrasive in suspension in a liquid
IPC: B24C5/00
Filed: 1965-01-21
Abstract: A system for the circulation of an abrasive in suspension in a liquid, such as water, more particularly for ultrasonic machining devices comprises a tank 1 with a convex conical base 2, means for projecting an abrasive therein firstly at the top of the tank by at least two adjustable nozzles 19, 20 and secondly at the top of the cone formed by the base by a conical rose 23, the supply conduits for the abrasive being connected to a distributer 12 which is symmetrically fed at its two ends from a pump delivery 9, another two conduits 25, 26 also being connected to the bottom of the conical part of the tank so that abrasive can return to the pump inlet. The arrangement of the parts of the system prevents any deposition of the abrasive at the bottom of the parts making up the system. The tank has a lower part 1 formed with the convex conical base 2 and an upper part 3 having a plurality of swivel joints 21 for supporting the nozzles 19, 20 which direct the abrasive in suspension to a workpiece placed or secured on a holder 5 supported by lugs 4 on the walls of the tank. The nozzles 19, 20 and the rose 23 which has apertures 24 on its underside are connected by separate conduits to the distributer 12, each end of which is separately connected by conduits 11 to the delivery 9 of a pump 6 having a rubber stator and worm.

Title: Reversible winding arrangement
IPC: D01H4/48
Filed: 1967-02-04
Abstract: In mechanism for withdrawing and winding-up the yarn in break-spinning apparatus, the rotation of which mechanism can be reversed for repriming the apparatus in the event of a break in the withdrawn yarn, the winding mechanism comprising a traversedrum, and the withdrawing mechanism comprising a pair of nip roilers, one of which is driven and the other is a pressure-roller, the pressure-roller is mounted so that it can be lifted off the driven roller to this end, it engages a working-member which is controlled by a device according to the direction of rotation of the traverse-drum, so that during the reverse rotation of the latter for re-priming, the withdrawing rollers are spaced apart. In Fig. 1, yarn 2 is withdrawn from the spinning-chamber 1 by nip rollers 3, 4 to be wound on a package 9 under the control of a traverse-drum 8. The roller is driven by the drum 8 which is itself driven by a motor 17. The roller 4 is mounted on a pivoted arm 5. The presence of yarn between the chamber and the nip-rollers is sensed at 15, and the direction of rotation of the roller is sensed at 14. When the yarn breaks, the sensing-device 15 supplies through a device 16, an impulse to the drive 17 causing it to reverse the direction of rotation of the roller 8, and accordingly of roller 3. When the drive 14 senses the reversal, a device 13 supplies an impulse to a member 11 which causes the arm 5 to pivot and raise the roller 4. In Fig. 2, the pressure-roller 4 is. carried by an arm 20 pivoted at 6. The driven roller 3 is keyed to a shaft 18, Fig. 3, and when the direction of rotation is reversed it displaces a cam 33 to pivot the arm 20 and raise the roller 4. The inside of the roller is hollow and provides a hub 22 with a profiled surface 23 cooperating with rollers 24 to form a one-way clutch between the roller and a ring 28 with a friction-pad 32 urged against a cam 33 by a spring 31. During the spinning operation, as the roller 3 is. rotated to withdraw the yarn, the clutch is disengaged, and the cam tends to rotate in direction opposite to that in which the roller is rotated under the influence of a spring 36 secured at one end to the cam and at the other to a fixed part 38. This tendency of the cam to rotate is restrained by the engagement of a pin 42 with a face 40 of a recess 39 in the cam. When the roller is backrotated for re-priming, the clutch is engaged and the cam is driven through the ring 30 and pad 32, the rotation of the cam being limited as the opposite face 41 of the recess engages the fixed pin 42. As the cam rotates, a profile 44 thereon engages the arm 20 and causes it to pivot and lift the roller 4.

Title: Sulphonates
IPC: C07C7/171
Filed: 1967-04-25
Abstract: Olefin sulphonates are prepared from olefins (e.g. C 10-22 ) which have been purified by treatment with sulphuric acid under conditions such that olefin sulphation and isomerization do not take place, followed by phase separation and treatment of the olefin layer with an absorbent (see Division C5). Sulphonation may be effected using an SO 3 /air mixture in a falling film reactor, a stirred tank reactor, or by atomizing the olefin in the SO 3 /air stream. The sulphonated products may be bleached with an aqueous sodium hypochlorite solution. They are useful in detergent compositions.

Title: Multi-source signal coupling system using hybrid junctions to compensate for source amplitude unbalance
IPC: H01P5/16
Filed: 1967-04-29
Abstract: In an electric circuit comprising at least one input and one output hybrid junction and an adjustable phase shifter in one of the paths connecting the input and output hybrid junctions, two input points of the input hybrid junction being connected (with or without relative fixed phase shift) to respective radio power sources and two output points of the output hybrid junction being connected to useful and dummy loads respectively, a circuit detects the amplitude difference of the signals from the radio power sources and automatically adjusts the phase shifter to maintain maximum ratio of power in the useful load to that in the dummy load. In an embodiment phase-locked transmitters T1, T2 of equal power feed a hybrid junction 10 connected to points 18, 19 and including an adjustable phase shifter 20 points 16, 17 are connected to an aerial 3 and dummy load 9 respectively. When the phase shifter is adjusted for 90 degrees shift the output signals reach hybrid junction 15 in phase and the aerial receives the combined power from both transmitters and none is lost to load 9. If the relative powers of the transmitters change the phase shifter is re-adjusted to give total power feed to the aerial. Automatic re-adjustment of the phase shifter can be derived from diodes 56, 58, D.C. amplifier 68 and reversible motor 72 a rate feedback is afforded by a generator 76. To cater only for a complete failure of one transmitter an " on-off " phase shifter is provided utilizing a trombone coaxial phase shifter, Fig. 1a (not shown). Transmitter phase-locking.-The outputs of probes 48, 50 are applied to a hybrid junction 52, one via a 90-degree phase shift. A phase shifter 43 is controlled by the voltage from a tapping on the resistor 52R to restore in-phase transmitter outputs by variation of varactorcontrolled phase shifter 43. In another embodiment each transmitter comprises sound and vision channels and associated diplexer, Fig. 3 (not shown). In a modification the sound units of both transmitters are connected to a first hybrid junction and the outputs of the hybrid junctions are diplexed via adjustable phase shifters to a third hybrid junction to which the aerial and dummy load are connected, Fig. 4 (not shown): should either vision transmitter fail, the system by phase shift re-adjustment can radiate the power from the remaining vision transmitter plus the power from both sound transmitters, and similarly in the case of failure of one sound transmitter &c. In one modification failure of either diplexer is catered for, Fig. 5 (not shown) in another modification concurrent failure of one transmitter and a diplexer is allowed for and utilizes two further hybrid junctions, Fig. 6 (not shown). An arrangement is described where there are three transmitters, Fig. 7 (not shown). Various alternative forms of hybrid junction may be utilized, Figs. 8, 9, 10 (none shown).
